A pulse tube refrigeration system includes a pressure wave generator generating continuous pressure wave of a working fluid: a regenerator having a low temperature end and a high temperature end connected to the pressure wave generator; a cold head connected at one end thereof to the low temperature end of the regenerator and producing a very low temperature; a pulse tube having a high temperature end and a low temperature end connected to the other end of the cold head; and a phase shifter adjusting a phase difference between a pressure oscillation and a displacement of the working fluid and transmitting an expansion work of the working fluid to the high temperature end of the regenerator in mechanical mode which is performed at the high temperature end of the pulse tube.
